Shumitect 真白牙膏 高濃度氟化物配方 1450ppm

I was skeptical about a toothpaste with no abrasive for whitening, but after a few weeks my teeth feel noticeably smoother and the sensitivity I usually get with cold drinks is almost gone. The 1450ppm fluoride blend seems to be doing its job without any harshness.

My teeth have been way less sensitive to cold drinks since I started using this, and the high fluoride content gives me peace of mind about cavities. It’s not abrasive at all, which was a nice surprise since my enamel is pretty thin.

I was skeptical about a toothpaste that promised to help with sensitivity, but after a week, sipping iced coffee no longer makes me wince. The 1450ppm fluoride content feels thorough without any harsh grit, and my teeth definitely look brighter.
